Fig. 3.is a fragmentary section illustrating the. action of a perforating plungerused in the said apparatus.

Referring to the drawings in which like characters designate like parts throughout ably circular in cross-section. The upper end of the casing is counterbored as .at 3 for with the arm 14, and which therebmproin with-a tube 1 5, which servesgto permit "of the withdrawal of..fl'uid from the recep- 'taclc 16 to-which the casing is afiiiredyhen a operation,- and in the tobeflesoribed.:.. The connecting means 'just' referred preferably consist of a gland 17 of steel,or. I .the like, which has a threaded .connection.f,.6;

.: {vides means for driving a conical head-.1 8v of. brass, or other suitablematerial, into the; recessed or countersunk end. 'of said arm,.to' efi'ect a tight joint therewith. The head 18 is axially apertured and is. preferably-se- )101 cured to the extremity of the tube 15,.by. being-brazed thereto, if'the said, tube made of copper or the like. -A couplinglor, ,nipple' 19 is, provided in connection with-then .j ljf I ireceptacle' and is preferably fixedly secured 1-10- thereto and threaded exteriorly for connection with the lower end of easing 1, said master hereinaf er-e51,

the reception of suitable packing 4, the latend being counterbored' and interionly threaded for that purpose.

follows: Assuming that the receptacle is j:

charged, or has been filled with fluid more ="1 S'under pressure and with its. v e dlscharge valveproperlysealed. The should be screwed in position upon the-colipling ornipple and the tube 15 will be connected to the arm 14 in the manner above described. All connections having been made fast the hand-wheel 8 may then be rotated clocliwise as viewed from above, until the lower extremity of the plunger encounters the lead seal. Continued rotation of said wheel will force the reduced end of the plunger-into and through this seal, cutting a button therefrom and forcing said -button through the vent or opening in the bottom of' the coupling; the body of the seal, however, being fixedly held in place in. said coupling by reason of its engagement with.

the seat in the interior of the coupling. If

not! the plunger be withdrawn by reversing. the rotation of the hand-wheel 8, the fluid may then pass through the vent and through the aperture in the seal into the chamber 2, and thence out' through the port 13 and through the-tube 15 to the point where it is intended to be used. Even though the pressure exerted by the fluid in the receptacle be very considerable, substantially no leakage Wlll occur by reason of the packing around the plunger, nor around the threads of coupling 19, which is prevented by the use of a suitable gasket 23 and" further when it is desired to stop the flow of fluid from the receptacle it is merely necessary to again drive the plunger downwardly through chamber 2 until the seat or shoulder 22 which is formed between the body of the plunger and its reduced portion, comes in contact with the deformable material of the seal which is disposed around the vent. The continued descent of the plunger will then further force this material to conform to the shoulder 2:2 of the lunger and will hence provide a very efective temporary seal for the receptacle. Of course the fluid may be withdrawn .in any desired quantities and as often as desired, and the receptacle may be effectively sealed after each withdrawal of fluid therefrom.

My apparatus is particularly adapted for use in connection with such fluids as liquid 'chlorin, and, of course, the materials of which the respective parts are composed,

should be adapted for use in connection with the fluid to be dispensed. For the seal form ing material I findthat lead is particularlywell adapted, this metal being practically unactedupon by many chemically'active fluids, while it possesses the requisite ductility to adapt it to be deformed and readily perforated in the manner above described.

What I claim, is:- I 1. The combination of a vented pressure fiuidholding receptacle with a deformable seal therefor and an apparatus for manipu-.

lating the latter, said apparatus comprismg a casing adapted to e secured to said receptacleat the vent thereof, aseal r eceiving part having a recess therein in com-"'* and open said vent.

said casing andadapted to deform said seal 4 95. 2. The combination of a ventedpressure fluid holding receptacle with a deformable seal therefor and an apparatus for manipu-- lating the latter, saidapparatus comprising a casingadapted to be secured to said receptacle at the ventthereof, a seal -receiving art having a recess therein in communicatlon with said vent, the bottom, of

said recess forming a seat for the seal, said' seal being of tenacious, ductile material and ,the lateral walls of said recess, and being ioutward displacement by the pressure of the fluid in said receptacle, said apparatus further comprising a plunger movable in said casing and adapted to deform said'seal and open said vent, said plunger having a MAX MAURAN.
